We retain information from 2 basic sources: external and internal. External sources are our perceptual processes such as sight, hearing, or becoming aware of something through the senses, whereas internal sources are involved with processes such as reasoning, imagination, and thought. When it comes to analzing the processes people use to determine whether information initially originated from an external or an internal source this is referred to as reality monitoring. Reality monitoring is accredited to be responsible for the distinction and confusion between memories for thoughts and memories for perceptions. There is much research examining reality monitoring and, more generally, source monitoring, identifying the factors that influence false memories. These studies have provided a foundation for perceiving differences in those susceptible to false memories and beliefs, such as vulnerability to social influence,impulsiveness , proneness to imagery. Recent studies and research focused on distinguishing both impaired and intact memory processes in individuals with autism, in order to investigate the central cognitive processes underlying autism. This paper will discuss if children with autism experience more difficulty distinguishing between real memories and false memories, and whether is it harder for them to communicate this information INTRODUCTIONSource monitoring attributes an individual’s ability to determine the origin of their memories. Typically the source of the memory is incorrectly connected to a specific recollected experience. The concept of pinpoints the factors that influence false memories such as similarity between sources, effects of association and schema, emotional focus and the criterion during recollection. SM can be separated into three categorizations. One form is the ability to distinguish memories derived from external sources. For example, if you were talking to both Jack or Jill when one of them made a statement, whether at a later time you can recall which of the two made the statement). Another form of source monitoring is the ability to distinguish internally developed memories. Internal memories are derived from an individual’s own activity. For example, when recalling a past conversation, you can distinguish statements you actually said from statements you thought about saying). The third form of source monitoring is the ability to distinguish memories obtained from internal and external sources. For example, when recalling a conversation with a person, you can remember which statements they made and statements you made. This form of source monitoring is referred to as reality monitoring.
